Real Time Analysis of Tracer Summaries to Change Tracer Behavior

摘要

Real time analysis of tracing data may identify functions for which tracing may be enhanced or reduced. A tracer that generates function-level data may have an aggregator that summarizes the data. Potential changes to tracing configuration may be identified by analyzing the summarized data to determine whether or not each function is being traced at a level commensurate with that function's impact to the summarized data. Those functions with little significant contribution may have their tracing reduced, while those functions with more significant contribution may have their tracing enhanced. The analysis of the summarized data may be performed in real time in some instances, causing a tracer to change the data collected while an application executes.
